SEPARABL-E BUTTON AND STUD.

SPECIFICATION forming part of Letters Patent No. 247,557, dated September 27, 1881.

Application filed January 17, 1881. (No motlel.) I

the cityand county of Providence, in the State of Rhode Island, have invented a new and useful Improved Separable Button and Stud. of which the'following is a specification.

My invention relates to a button or stud formed in two parts, the one part consisting of a shoe and hollow elliptical post provided with a collar and notches near its upper end, and the other part consisting of a box formed to receive the setting or stone of the button-face, and containing a lining, to which is attached a projecting solid post adapted toenter the aforenamed hollow post when the ,two parts are to be united. This lining is held in place by a back plate through a slotted opening, in which plate said solid post projects, said opening being enlarged slightly at the sides to receive the hollow post, which has corresponding enlargements on its sides to enable it to receive the solid post.

In the chamber formed by the lining and the back plate Iplace sprin g-oontrolled lockin g devices, which are released by pushers extending laterally through the sides of the box.

The detail of construction and arrangement I of the several parts is more fully illustrated in the accompanying drawings, in which- Figure 1 is a plan looking from under side of the button, the back plate being removed, and shows also cross-section of hollow post through the notches near its upper end. Fig. 2 is a vertical central section on line 00 00, Fig. 1. Figs. 3 and 4 represent the back plate. Fig. 5 is a vertical central section of the lining on a line at right angles with line 00 m. Fig. 6 is a plan of lining. Fig. 7 is a plan of the shoe 5 Fig. 8, a side elevation of the shoe, showing the notches near its upper end, and Fig. 9 an edge elevation of the shoe.

Arepresentsthehollow elliptical post,for1ned, without any joint,of a single piece of metal, attached to the shoe 0, and provided near its upper end with a shouldered rim or collar, a, and the notches e c, Fig. 8. The collar a serves the doublepurpose of determining the distance which the post enters the head of the button and of preventing the post A from falling out of a button-hole into which it has once been inserted.

The hollow post A is enlarged in its crossseotion, as shown in Fig. 7, so as to form a circular chamber to receive the solid post t, which solid post, as well as the spring-controlledlocking devices, is secured to the lining m. This lining m is held into the head of the button by a back plate, n, which has an orifice corresponding in outline with the post A. The edges of the post A, being less in cross-section than the body of the post, form lips, which are engaged by spring-controlled locking devices after the post is inserted in the orifice of the plate at and turned quarter round, at which time the notches e c engage the sides of the orificein the plate a, atright angles to the'same, and prevent the post from disengaging itself unless it is turned until it coincides with the orifice, when the post can be separated from the button-head, Fig. 2;

I use for the spring-controlledlockin g device a'continous wire provided with offsets to engage the lips e e, and crossed so that its ends extend in opposite directions through the sides of the head to form pushers, Figs. 1 and 2.

I do not, however, claim as new herein a spring-controlled locking device formed of one continuous wire crossed to form pushers, as the same is now secured to me by Letters Patent dated October 14, 1879.

It is obvious that the post A may be of any dimensions or form between the shoe 0 and lips c 0, provided the head of the post is shorter one way than it is the other, andis adapted to engage the back plate a alter being inserted through the orifice in the same and turned at an an gle thereto, said orifice always corresponding in outline with the post-head. It is also immaterial whether the lips c c are simple projections attached to a round post to form a head of the shape described, or whether the posthead and lips are one continuous piece, provided the post-head, however constructed, is shorter one way than it is the other and adapted to operate as already described. I claim a post with such a head as a part. of my invention.

In operating my invention the part A is inserted through the orifice in the platen as far as the shouldered collar awill allow. It is then given a quarter-turn in either direction, when the lips c c crowd the locking devices apart until said lips are engaged by the offsets, which then hold the post securely in that position.

To release the post A it is necessary to unlock it by means of the pushers :v x, and then turn it in either direction until it and the orifice in plate n coincide.

I claim and desire to secure by Letters Patcut- 1. In a separable button or studin which the shoe-post and the head have free and complete axial movement relatively to each other in either direction, the shoe-post provided with a head the two main diameters of which are of unequal length, combined with the back plate 01, provided with the orifice corresponding in outline with the post-head and springcontrolled locking devices, which look said post at right angles to said orifice and are disengagc'dbypushers extendingoutward through the button-head.

2. A hollow elliptical post, A, provided with a shouldered collar, a, notches e a, and lips ca, as shown and described, combined with aplate, it, provided with an orifice corresponding in outline with the post A, and a solid post, t, immovably attached to the lining or head of the button.

3. The hollow elliptical post A, formed of one piece of metal without any joint, and provided with a shouldered collar, a, notches c e, and lips c a, less in their cross-section than the body of the post A, in combination with a shoe, 0, as shown and described.
